Abstract

L'invention porte sur un dispositif d'affichage. Le dispositif d'affichage comprend une plaque de guidage de lumière, une source de lumière disposée sur une surface latérale de la plaque de guidage de lumière, un élément de conversion de lumière disposé entre la source de lumière et la plaque de guidage de lumière, et un premier élément d'adhérence étroitement fixé à la plaque de guidage de lumière et à l'élément de conversion de lumière. Une couche d'air entre la source de lumière et la plaque de guidage de lumière est retirée par les premier et second éléments d'adhérence afin d'améliorer une efficacité d'incidence de lumière dans la plaque de guidage de lumière.
